Two compounds are standing at the same temperature. Compound "A" is evaporating more slowly than compound "B." According to the Kinetic Molecular Theory, which assumption can be made? A.) Compound B has a greater average kinetic energy. B.) Compound A has a greater average kinetic energy. C.) Compound A may have a lower molecular weight. D.) Compound B may have a lower molecular weight.

Option D) Compound B may have a lower molecular weight.

Explanation:

Compound A and B are standing at the same temperature yet compound A is evaporating more slowly than compound B.

This simply indicates that compound B have a lower molecular weight than compound A.

This can further be seen when gasoline and kerosene are placed under same temperature. The gasoline will evaporate faster than kerosene because the molecular weight of the gasoline is low when compared to that of the kerosene.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
